4 SHEETS SHEET 4,

, v jkzmwi m W MU w 7? w W MW are alternately raised and lowered so as reciprocation for each two revolutions of the plate cylinder P, or forevery two sheets printed by the machine. By means of thisriving arrangement the carriage lwillj be reciprocal-ted at the desired time and will,

for the major portion of its stroke be trav .elcdat uniform speed, while the wrist pin 3 is moving between the sprockets 3 and 3, but will be slowed dowmstopped and reversed with a. true crank motion at each end of its stroke, while the wrist pin 3 is assing around sprocket 3i or 3. y 3 Xi opposite sides of the shaft 2 are mounted vertically movable bars 4 and 5; the bars 4t have rack portions 4 which mesh with gears 52 on the shaiit 2, and the bars 5 have rack portions 5 which also mes-h with opposite sides ofthe gears 2 so that as the gear 2 oscillates one set of rack bars is raised while the other set is depressed.

The rack bars 4 carry rollers Q ifi 'at their lower ends and the rack bars t3 carry rollers 5 5. The bars are guided in suitable brackets attached to-the frame. Journaled in these brackets at one side of and above the shaft'fl is e set of tape rollers 4, 4 4, 4 and iournaled in the brackets at the o posite side of and above shaft 2, is a set or tape rollers 5 5f, 5, 5 Journaled in opposite ends of the carriage 1 are tape rollers 4 5 respectively. A set of endless tapes 4 run over roller 4*, to and over roller l, down tinder roller 43, up over roller i down under'roller 4, up over roller 4, down and around roller 4?, and back to roller 43. A similar set of tapes 5 run over roller 5 up over roller 5*; to and around roller 5 and. thence back to roller 5 as the carriage 1 recipro'cates the rollers 4e. 5 are alternately moved to and fromthe rollers 45 ,5 3 and the rack bars 4 and 5 to take up or g ve out tape, in or from the loops on the rollers on said rack bars, as may be required by the movement or the rollers t 5%, For'example, asroller 4 moves inward the rollers d 4;? are lowered so as to take up the loopof tape paid in from the roller t; and simultaneously the roller 5 moves outward and the rollers- 5, 5 rise and pay out from their l S enough tape to supply the elongation of 1.9 loop around roller 5" (tee Fig. 1):

Intermediate rollers-53 t is a tape propelling roll 8 which is journa-led in arms 6 ivoted ateon bracketsattaohed to the frame. This propelling roll is adapted to be alternately hronghtinto-contact with-the tape rollers 49 or 5* so es to propel the sets of tapes running? thereover- The roller 8 may be driven and rotated in the proper direction and time by means of a pinion 6 thereon meshing with a rack 1 on the adjacent side bar of the carriage 1.; The propelling roller 6 maybe moved into contact- With the tape rollers 4 or 5 at the proper time, and be held in contact therewith, by means of a pitman 6 having a roller 6 en gaging a raoecam 6 attached to a stubshaft 6 carrying a gear 6' which may be driven by a pinion 6* attached to a shaft 6, on which is a gear 6 that meshes with a gear 6 which may be fixed on the main drive shaft 6" of the machine. The reel '1 may have agear T also meshing with the ear 6.

Attached to the arms 6, aredepending arms 6 which carry clamp members 6 which operate between-the adjacent vertical runs of the tapes P, 5, and between stop bars 4, 5 adjacent tapes 4:,and 5, see Figs. 1 and 2. These stop bars 4, 5 are so lo cated that when the propelling roller 6 is moved into contact with the roller 5 it will drive tapes 5 and clamp 6 nips tapes e againststop bar 4 and stops the linear travel of tapes t over their rollers, except such as may be required to compensate for the extension and contraction of their loops. Similarly, when propelling roller 6 is moved into contact with tape roller 43 in order to drive tapes 4:, the tapes 5* are nipped by the clamp 6 against stop bar 6 and heldagainst linear travel; except such as may be required by the extension and contraction of the loops in said tapes. The tapes i are held only when the roller 4: is moving- ,inward and the tapes 5 are so held only when the roller 5 is moving inward. Whenroller @for example is moving inward and the roller 6 drives tapes 5, andthe tapes 4* 7 driving roller 'Ztfrom'roller 4:. l thovev the table (Z is a similar set of rider tapes 8 running over rollers 8 8 and driven by a cross belt 18 from the taperoller 5.

When the parts are in theposition shown in Fig. lit may hejissumed that a-sheet has been taken. from. reel t and carried out by tapes 5 overthd table 0?. Another sheet is then ready to be delivered by reel T to the I tapes .4. The'carriage will then move to the right, and as the carriage starts roll 6 is, movedover against roll 4, (see Fig. 2)

'and the clamp 6 nips tapes 5 against stop 5. As the carriage moves to the right tapes tiere traveled atthe s eed of the cylinder, and. the. sheet received 'rrom'reel T is carried out on tapes t toward roller 49, to andover table D, the sheet coming into proper posiare held from travelin over the rolls 4e, 4.
